The Address was delivered at the dedication of the Soldiers’ National Cemetery in Gettysburg, Pennsylvania, on the afternoon of Thursday, November 19, 1863, during the American Civil War, four and a half months after the Union armies defeated those of the Confederacy at the decisive Battle of Gettysburg. In just over two minutes, Lincoln invoked the principles of human equality espoused by the Declaration of Independence and redefined the Civil War as a struggle not merely for the Union, but as “a new birth of freedom” that would bring true equality to all of its citizens, and that would also create a unified nation in which states’ rights were no longer dominant. Throughout history, some books have changed the world. They have transformed the way we see ourselves – and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives – and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
